An Introduction to Nucynta Side EffectsJust like any medicine, Nucynta™ (tapentadol) can cause side effects. However, not everyone who takes the medication will have problems. In fact, some people tolerate it quite well. If side effects do occur, in many cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Nucynta. Your healthcare provider can discuss a more complete list with you.)
